最近是不是发送图片又不行了？

ConnectionError: HTTPSConnectionPool(host='file2.wx2.qq.com', port=443): Max retries exceeded with url: /cgi-bin/mmwebwx-bin/webwxuploadmedia?f=json (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 11001] getaddrinfo failed',))

Start by reproducing image sending and trace the Python image-upload path that requests file2.wx2.qq.com/cgi-bin/mmwebwx-bin/webwxuploadmedia?f=json. No source file or test is named, so inspect how this endpoint is selected and verify whether uploads succeed or fail with the reported DNS error; done means the failure is fixed or clearly documented as an external service limitation.
